Document Type: Proceeding Paper

Part of: Microcomputer Applications in Transportation III


This paper presents a comparative analyses of the Microcomputer Compatible Florida Standard Urban Transportation Modeling Structure (Micro-FSUTMS) performance with its UTPS mainframe computer-based counterpart. The Micro-FSUTMS was used to simulate traffic and ridership on a multi-modal transportation system including a 48-mile long rail transit system proposed for Tampa Bay Area. The modeling system was comprised of a 700-Traffic Analysis Zone (TAZ) system encompassing Hillsborough County. The comparative analyses were conducted by using a common set of input data files and parameters in both Micro-FSUTMS and UTPS mainframe computer-based modeling systems. Study results are discussed.
